🏢 About Mozilla

Mozilla is a mission-driven organization behind Firefox, dedicated to a healthy, open internet. It's a unique place where your work supports not just a product but a cause—internet privacy and accessibility.

About This Role

As the Executive Assistant to the CFO and VP of Finance, you'll be the linchpin of the finance leadership team, ensuring executives can focus on strategic priorities. Your role involves orchestrating complex calendars, preparing for Board cycles, and managing confidential information with discretion. It's a high-impact position where your organizational skills directly enable financial strategy and operational excellence.

💡 A Day in the Life

Start by reviewing the CFO's calendar for the day, resolving any conflicts, and preparing agendas for key meetings. Mid-morning, coordinate logistics for an upcoming offsite and handle expense reports. Afternoon might involve drafting a board briefing, following up on action items from the morning's finance team meeting, and proactively planning the next week's schedule.
